PURPOSE: A DC-DC converter, an organic electric field light emitting display apparatus, and an operation method thereof are provided to detect high temperature arranged in an abnormal state of the DC-DC converter, thereby stopping supply voltage output. CONSTITUTION: A plurality of pixels is comprised in order to arrange a plurality of scanning lines in a transverse direction and a plurality of data lines in a row direction. A power supply part(500) generates a DC power source from an external power source. A DC-DC converter(400a) receives the DC power source from the power supply part. The DC-DC converter generates first supply voltage and second supply voltage in order to supply to a pixel part. |
